[13] One of the oldest recorded alligator lives was that of Saturn, an American alligator who was hatched in 1936 in Mississippi and spent nearly a decade in Germany before spending the majority of its life at the Moscow Zoo, where it died at the age of 83 or 84 on 22 May 2020. It is common to use several wraps of duct tape to prevent an adult alligator from opening its jaws when being handled or transported. [64], Both the United States Fish and Wildlife Service (USFWS) and state wildlife agencies in the South contributed to the American alligator's recovery. A lone American alligator was spotted for over 10 years living in a river north of Atlanta, Georgia. [55] During respiration, air flow is unidirectional, looping through the lungs during inhalation and exhalation;[56] the American alligator's abdominal muscles can alter the position of the lungs within the torso, thus shifting the center of buoyancy, which allows the American alligator to dive, rise, and roll within the water. The alligator now has a status of "threatened due to Legal Status. Alligators first appeared during the Oligocene epoch about 37million years ago. By 1960, however, alligators had been completely eliminated from much of their former range. An alligator with an immobilized tail cannot perform a death roll. Biologists recently estimated that the state has between 32,000 and 38,000 alligators, far fewer than either Florida or Louisiana. Here's a complete rundown. The victim's neighbor can be heard on a 911 call as Gloria Serge was dragged underwater. American alligators prevent predatory mammals from reaching island-based rookeries and in return eat spilled food and birds that fall from their nests. American alligators occasionally prey on large mammals, such as deer, but usually do so when fish and smaller prey levels go down. [74] In the limestone depressions of cypress swamps, alligator holes tend to be large and deep, while those in marl prairies and rocky glades are usually small and shallow, and those in peat depressions of ridge and slough wetlands are more variable. [132] According to the Florida Department of Agriculture and Consumer Services, raw alligator meat contains roughly 200 Calories (840 kJ) per 3-oz (85-g) portion, of which 27 Calories (130 kJ) come from fat. In the future, possible American alligator populations may be found in areas of Mexico adjacent to the Texas border. [113] Observers of large bellowing choruses have noted they are often felt more than they are heard due to the intense infrasound emitted by males. [106] Their vocal folds consists of epithelium, lamina propria and muscle. [14][15] Another one of the oldest lives on record is that of Muja, an American alligator who was brought as an adult specimen to the Belgrade Zoo in Serbia from Germany in 1937. Bondavalli, C., and R. E. Ulanowicz. And though census numbers are hard to pin down, the plan. They are grouped in the family Alligatoridae with the caimans. The baby alligator's egg tooth helps it get out of its egg during hatching time. This listing provides federal protection for alligators but allows state-approved management and control programs. The high walk is an up-on-four-limbs forward motion used for overland travel with the belly well up from the ground. [35][36] Their stomachs also often contain gizzard stones. Oklahoma (100-200) There is a tiny population of alligators that live in certain southern regions of the state. "Gators" has been the nickname of the University of Florida's sports teams since 1911. The 11 feet-long gator was later captured and killed. Additionally, it weighs considerably less, with males rarely over 45kg (100lb). Subsequent conservation efforts have allowed their numbers to increase and the species was removed from endangered status in 1987. They play an important role as ecosystem engineers in wetland ecosystems through the creation of alligator holes, which provide both wet and dry habitats for other organisms. Watch on. The bellows of male American alligators are accompanied by powerful blasts of infrasound. (2010). The American alligator is a stunning example of a species that has fully recovered in large part due to protections provided by the Endangered Species Act. [6] The full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds. Unlike the other extinct alligator species of the same genus, the fossil skull was virtually indistinguishable from that of the modern American alligator. Alligator in captivity The states that have alligators are Florida, Mississippi, Texas, Louisiana, Alabama, North and South Carolina, and Georgia. Adult American alligators held the record as having the strongest laboratory-measured bite of any living animal, measured at up to 13,172N (1,343.2kgf; 2,961lbf). [65] Females and juveniles are also found in Carolina Bays and other seasonal wetlands. [46] Given that female American alligators have relatively higher survival rates at an early age and a large percentage of given populations consists of immature or young breeding American alligators, relatively few large mature males of the expected mature length of 3.4m (11ft 2in) or more are typically seen. [22], In 2013, American alligators and other crocodilians were reported to also eat fruit. In 1967, the American alligator was listed as an endangered species (under a law that was the precursor Endangered Species Act of 1973), since it was believed to be in danger of extinction throughout all or a significant portion of its range. Wetland Ecology: Principles and Conservation (2nd edition). The American Alligator population was dramatically reduced by the 1950s and 1960s and a majority of the wild population was likely lost (USFWS 2008). The animal's dark skin is armored with small, bony scales called scutes. [124], American alligators are capable of killing humans, but fatal attacks are fairly rare. Alligator Data and Reports Alligator management programs implemented by FWC emphasize the conservation of alligator populations for their ecological, aesthetic, and economic values while providing for public use and safety. [105], An American alligator is able to abduct and adduct the vocal folds of its larynx, but not to elongate or shorten them; yet in spite of this, it can modulate fundamental frequency very well. The right to left shunt of the heart in alligators means the circulatory system will recirculate blood through the body instead of back to the lungs. According to the 2022 annual count, the U.S. population of Mexican wolves has increased, raising the total number of wolves in the wild to a minimum of 241 animals, a 23 percent increase. [24] Other prey, including snakes, lizards, and various invertebrates, are eaten occasionally by adults. [19] Weight varies considerably depending on length, age, health, season, and available food sources. [10] It is distinguished from the sympatric American crocodile by its broader snout, with overlapping jaws and darker coloration, and is less tolerant of saltwater but more tolerant of cooler climates than the American crocodile, which is found only in tropical and warm subtropical climates. 1998. [12], No average lifespan for an alligator has been measured. Mistaken identity leading to an attack is always possible, especially in or near cloudy waters. [51] Alligators also have highly folded mucosa in the lining of the intestines to further aid in the absorption of nutrients. American alligators are often less aggressive towards humans than larger crocodile species, a few of which (mainly the Nile and saltwater crocodiles) may prey on humans with some regularity. 2010. [115] The female builds a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. American Alligator (Alligator mississippiensis) An ESA success story Photo: Expert Help. In Florida, feeding wild alligators at any time is illegal. [2] Later English spellings of the name included allagarta and alagarto. The species is the official state reptile of three states: Florida, Louisiana, and Mississippi. Alligator attacks an 85 year-old grandmother walking her dog in a retirement community in Fort Pierce, Florida. Oklahoma is home to between 100-200 individuals, but they constitute a stable population. [62], American alligators are currently listed as least concern by the IUCN Red List, even though from the 1800s to the mid-1900s, they were being hunted and poached by humans unsustainably. These alligators are practically impossible to find in the wild. Such general rules include: Alligator in the Everglades National Park, Alligator in the Canberra Zoo in Australia, Juvenile alligator found in Everglades National Park. The wild population of Mexican wolves in the United States continued to grow in 2022. ", http://www.flmnh.ufl.edu/herpetology/links/cooperative-feeding, "Demographic and geographic variation in food habits of American alligators (, "Subglottal pressure and fundamental frequency control in contact calls of juvenile Alligator mississippiensis", "Functional morphology of the Alligator mississippiensis larynx with implications for vocal production", https://defenders.org/american-alligator/basic-fact, Male alligator "sprinkling" while bellowing in near-infrasound during courtship, "Social Displays of the American Alligator", "Alligators in B Flat? Members of this superfamily first arose in the late Cretaceous, about 10065 million years ago (Mya). Females are smaller, measuring 2.6 to 3m (8.5 to 9.8ft) in length.

[46] Alligators have a two-part stomach, with the first smaller portion containing gastroliths. Miami MetroZoo in Florida also has a breeding pair of Chinese alligators. Sounds ranged from 50 to 1200Hz. [22][23], During the 19th and 20th centuries, larger males reaching 5 to 6m (16ft 5in to 19ft 8in) were reported. However, they are on average one of the most darkly colored modern crocodilians (although other alligatorid family members are also fairly dark), and can be reliably be distinguished by color via their more blackish dorsal scales against crocodiles. [128] In May 2006, American alligators killed three Floridians in less than a week. However, these claims are largely based on assumptions and observations of juvenile and young adult crocodilians, and recent studies are beginning to contradict this claim. Additionally, several extinct species of alligator are known from fossil remains. Alligators in the wild can live up to 70 years; some in captivity may live even longer. Such behavior has been witnessed, as well as documented from stomach contents, with the American alligators eating such fruit as wild grapes, elderberries, and citrus fruits directly from the trees. Usually, terrestrial hunting occurs on nights with warm temperatures. Fish and Wildlife Service pronounced the American alligator fully recovered. The states with the most alligators are Louisiana, Florida, and Alabama. [22], Additionally, American alligators have recently been filmed and documented killing and eating sharks and rays; four incidents documented indicated that bonnetheads, lemon sharks, Atlantic stingrays, and nurse sharks are components of the animal's diet. [29][30][31], Although the alligator has a heavy body and a slow metabolism, it is capable of short bursts of speed, especially in very short lunges. Adult American alligators also spend considerable time hunting on land, up to 160 feet (50m) from water, ambushing terrestrial animals on trailsides and road shoulders. [117] The female remains near the nest throughout the 65-day incubation period, protecting it from intruders. Baton Rouge: Louisiana State University Press. As human populations increase, and as they build houses in low-lying areas, or fish or hunt near water, incidents are inevitable where humans live near American alligators and their habitats. Even with medical treatment, an American alligator bite may still result in a fatal infection.[126]. Like many reptiles, alligators reach a larger size in Florida and other southern latitudes, sometimes reaching 15 feet. The American alligator is a relatively large species of crocodilian. Unlike an American crocodile, which would immediately succumb to the cold and drown in water at 45F (7C) or less, an American alligator can survive in such temperatures for some time without displaying any signs of discomfort. [7], The genus Alligator belongs to the subfamily Alligatorinae, which is the sister taxon to Caimaninae (the caimans). [136] The mascot stuck, and was made official in 1911, perhaps because the team captain's nickname was Gator. In some cases, larger alligators are known to ambush dogs, Florida panthers and black bears, making them the apex predator throughout their distribution. The role of the alligator in shaping plant communities and maintaining wildlife in the southern Everglades. The American alligator is classified by the US Fish and Wildlife Service as similarity of appearance to a threatened taxon. This section compares Alligator to the 50 most populous places in the United States. In order to understand and properly manage Texas's alligator population, TPWD Wildlife Division conducts extensive studies in the state on the number, character and harvest of alligators every year. 10. By the way, Florida declared the alligator their official state reptile in 1987. [72], American alligators primarily bask on shore, but also climb into and perch on tree limbs to bask if no shoreline is available. In April and May, alligators form so-called "bellowing choruses". [87], If an American alligator's primary food resource is not available, it will sometimes feed on carrion and non-prey items such as rocks and artificial objects, like bottle caps. Virginia Living Museum. This is not often seen, since if disturbed, they quickly retreat back into the water by jumping from their perch. On spring nights, American alligators gather in large numbers for group courtship, in the aforementioned "water dances". [112] Large bellowing "choruses" of American alligators during the breeding season are commonly initiated by females and perpetuated by males. [75], The teeth of the American alligator are designed to grip prey, but cannot rip or chew flesh like teeth of some other predators (such as canids and felids), and depend on their gizzard, instead, to masticate their food. An alligator measuring 19 ft. 2 in. [88], Other animals may occasionally be eaten, even large deer or feral wild boars, but these are not normally part of the diet. Large American alligators feed heavily on nutria, so American alligators may not only control nutria populations in Louisiana, but also prevent them spreading east into the Everglades. The two extant species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis). The sprawl is a forward movement with the belly making contact with the ground and is used to transition to "high walk" or to slither over wet substrate into water. This strategy, which is shared by the mugger crocodile, is particularly effective during the nesting season, in which birds are more likely to gather appropriate nesting materials. [52], During brumation the process of digestion experiences changes due to the fasting most alligators experience during these periods of inactivity. [29], American alligators do not normally reach such extreme sizes. An alligator, or just gator, is a large reptile in the Crocodilia order in the genus Alligator of the family Alligatoridae. Smaller alligators can often be found in large numbers close to each other. Juveniles can perform a high-pitched hatchling call (a "yelping" trait common to many crocodilian species' hatchling young)[109] to alert their mothers when they are ready to emerge from the nest. Florida . Population by Place in the United States. Rootes, W. L., & Chabreck, R. H. (1993). After the female lays her 20 to 50 white eggs, about the size of a goose egg, she covers them with more vegetation, which heats as it decays, helping to keep the eggs warm. [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. Wolfe, J. L., D. K. Bradshaw, and R. H. Chabreck. Alligator feeding habits: New data and a review. These microorganisms can be found in the high surface area of the mucosa folds of the intestines, as well as throughout the digestive tract. Alligators have muscular, flat tails that propel them while swimming. [59] Louisiana has the largest American alligator population of any U.S. state. Both sexes may den underneath banks or clumps of trees during the winter. Adult alligators are black or dark olive-brown with white undersides, while juveniles have bright yellow or whitish stripes which sharply contrast against their dark hides, providing them additional camouflage amongst reeds and wetland grasses. [110] Males are known to use infrasound during mating bellows. Large adult American alligators tend to be relatively robust and bulky compared to other similar-length crocodilians; for example, captive males measuring 3 to 4m (9ft 10in to 13ft 1in) were found to weigh 200 to 350kg (440 to 770lb), although captive specimens may outweigh wild specimens due to lack of hunting behavior and other stressors. In mature males, most specimens grow up to about 3.4m (11ft 2in) in length, and weigh up to 360kg (790lb),[7] while in females, the mature size is normally around 2.6m (8ft 6in), with a body weight up to 91kg (201lb). The type of food eaten by alligators depends upon their age and size. The Chinese alligator currently is found in only the Yangtze River valley and parts of adjacent provinces[19] and is extremely endangered, with only a few dozen believed to be left in the wild.
